518 THE DEVONIAN PERIOD. 



woody axis traced in a brighter line of graphite, occur in this 

 bed, but always in fragments. — Cordaites Robbii, Daws. Ex- 

 tremely abundant, and very fine specimens may be obtained, 

 especially from the upper part of the bed, and rarely specimens 

 showing the base or the apex of the leaf. — Cyclopteris obtusa, 

 Lesqx. Occurs very abundantly in detached pinnules. — Cychp. 

 varia, Daws. Rare. — N. polymorpJia, Daws. Extremely abun- 

 dant, never inlarge fronds. — Sphenopleris Hazninghausii, Brongn. 

 Quite abundant, often in fine fronds. — S. marginata, Daws. 

 Abundant, in fine fronds. — S. Harttii, Daws. Very rare. — The 

 original specimen came from this bed. — S. Hitchcockiana, 

 Daws. — Hymenophyllites Gersdorffii, Goeppt. Rather rare. — 

 H. obtusilobus, Goeppt. Rare. — H. curtilobus, Daws. — Pecop- 

 teris (Alethopteris) discrepans, Daws. Amongst all the abun- 

 dance of plants afforded by Bed No. 2, I have detected only 

 one or two pinnules of this fern, which appears first in abun- 

 dance in Bed No. 3. It is afterwards one of the most common 

 species. — Pecopteris ingens, Daws. Very rare, only two or three 

 fragments of pinnules having been found. — Trichomanites (?) 

 — only a single specimen, probably, as Dawson has suggested, 

 only the skeleton of a fern. — Cardiocarpum cornutum, Daws. 

 Abundant, and very finely preserved, never attached. — C. 

 obliquum, Daws. Quite abundant, also never attached. — 

 Trigonocarpum racemosum, Daws. Rare. — Eurypterus puli- 

 caris, Salter. The occurrence in Bed No 2 of this minute 

 Crustacean w r as first detected by my friend Mr George 

 Matthew. It is very rare, not more than four or five specimens 

 having been found by Messrs Matthew, Payne, and myself, at 

 the time of the description of the species by Salter. I have 

 since that time succeeded in collecting nearly twice as many 

 more, some of which appear to belong to a new species. — 

 Amphipeltis paradoxus, Salter. The specimen figured in 

 Salter's paper was found by Professor Dawson and myself, in 

 breaking a piece of shale in my cabinet, that came from this 

 bed. Only one other specimen has since been obtained. It 

 consists of two or more of the thoracid segments, and was 

 collected by Mr Lunn. It is in the collection of the Natural 

 History Society of New Brunswick. In addition to the above 

 species, this bed has afforded the following : — Cyclopteris, sp. 

 nov. — Xeuropteris, sp. nov. A single specimen collected 

 by Mr Lunn. — Sjjhoiopteris, sp. nov. — Spirorbis, sp. (?) 

 The leaves of Cordaites in the upper part of the bed are as
